nonparametric density curve. e normal density curve is dotted and the

smoothed density is solid. e nonparametric density estimate is much

smoother than the histogram and may do a better job of showing the

nature of the probability model underlying the data. We will discuss how

we can test statistically whether a given set of data follow a particular pdf

in Chapter 9.

2.3 BOX AND WHISKER PLOT

e next plot that we consider is the box and whisker plot. is plot gives

a quick view of many essential features of a data set; in particular, the box

and whisker plot is useful for identifying ...
